96 yr old w/muscle invasive bladder cancer

I am a little confused by your narrative.  There is no evidence of cancer and yet the urologist wants to respect “more of the tumor?”  And then he would prescribe BCG.?    What did the pathology report say
after the first TURB?  Was the tumor low grade or high grade?

Because the current urologist does not have hospital privileges, it is difficult to see how he is going to do further resection.

if he is getting a second opinion, I would want to wait until after that before additional treatment.

Sounds like your Dad is doing well for 96 and has good quality of life! Heck, he handled one TURB ok so maybe that will work if he needs another peek and the BCG.... you can always try and start and quit if it causes problems. Is there some tumor left? Pat yourself on the back as a good caregiver!
